摘要： A pole actuation booster mechanism for a four-poles low voltage circuit breaker, which includes: a first operating member adapted to be operatively connected to the operating shaft of the circuit breaker and moving together with said shaft during its rotation from an open position to a closed position, and vice-versa, of said circuit breaker over a range of movement having a first, a second and a third portion of movement, the first operating member having a first operating end; an operating assembly including at least an elastic element operatively connected to a lever, the first operating member being disengaged from said operating assembly during the first portion of its movement and engaged with the lever during the second and third portions of its movement. During a closing operation of the circuit breaker the first operating member moves first along the first portion of movement driven by the operating shaft and disengaged from the operating assembly, then moves along the second portion of movement driven by the operating shaft and engaged with the lever and transmitting energy to the operating assembly; and finally moves along the third portion of movement driven by the lever and transmitting energy to the operating shaft.

摘要： Described herein is a switching apparatus for low or medium voltage electric grids, which includes one or more electric poles. Each electric pole includes: an outer casing defining an internal volume of the electric pole; a fixed contact assembly accommodated in the internal volume of the electric pole and including a fixed contact member extending along a longitudinal axis of the electric pole; at least one movable contact assembly accommodated in the internal volume of the electric pole; an actuation member accommodated in the internal volume of the electric pole and arranged coaxially and externally relative to the fixed contact member, so that the fixed contact member passes through the actuation member along the longitudinal axis. The actuation member is slidingly movable along the fixed contact member. When moving between the first and second actuation positions, the actuation member transiently couples to each trip mechanism to actuate the trip mechanism.
